Helmet system and safety device for use with a helmet

ABSTRACT

A helmet system has a restraint feature for deterring neck injuries that includes a helmet having an attachment member at the rear of the helmet and a tether coupled to the attachment member at the rear of the helmet. The tether couples the helmet to a part of the body of a user in order to limit movement of the helmet. A safety feature for use with a helmet in order to deter neck injuries includes a tether having a first connector at one end for fixedly mating with a helmet and a second connector at the other end for mating with a part of a body of a user. The tether is positionable in the rear neck area of a user.

FIELD

The examples described herein concern a helmet and a safety device for use with a helmet that can be utilized to help deter common head and neck injuries in contact sports.

BACKGROUND

Head and neck injuries in contact sports may occur when a player bends their neck down in order to contact another player. The force applied from this type of movement and contact can result in head and neck injuries. FIG. 1 shows a prior art football helmet 2 positioned on a user's head and the motion that can occur when a user drops their head down. The chin 4 hits the chest 6 and this can result in neck 8 injuries, particularly if a player hits another player in this position. In addition, players will often drop their heads in order to engage in a head-to-head collision. This is dangerous and, in addition, to leading to neck 8 injuries, can lead to head injuries, such as concussions.

SUMMARY

A helmet system having a restraint feature for deterring injuries is disclosed and described herein. A safety feature for use with a helmet in order to deter injuries is also disclosed and described herein.

DETAILED DESCRIPTION

An example helmet system 10 is described herein. The example helmet system 10 assists in restraining a user's neck 8 and chin 4 from bending forward until it hits the user's chest. Many neck and head injuries occur in sport when user's lower their heads against an opponent. The example helmet system 10 helps to prevent or at least deter such injuries by providing a safety device, such as a tether 14, that can prevent or deter a user from bending their chin 4 downwardly until it hits their chest, breastbone, or shoulder pads 6. The example helmet system 10 provides a helmet 12 that utilizes a device to prevent a wearer from being able to bring their chin 4 to their breastbone 6 by restraining movement of the chin 4 and neck 8 in relation to the shoulder pads and/or the wearer's chest 6.

The example helmet system 10 utilizes a known helmet 12 and attaches a tether 14, such as a strap or cord, to the rear 16 of the helmet. The tether 14 may be attached to back of the player's shoulder pads 18, in the case of football, or can be attached to a body harness 20 that is secured around a player's torso 22 or midriff. The tether 14 may be a plastic strap, a rope, a cord, a fabric strap, or any other type of elongated flexible, but preferably non-stretchy member. The tether 14 is coupled to the helmet 12 at a first end and to the user's body at the other, second end. The tether 14 may be coupled between the helmet and the user's body such that some slack is in the tether 14 in order to permit some forward movement of the chin, but not enough movement to permit the user's chin to contact their chest. The tether 14 may be adjustable so that the same or similar tethers 14 can be used for different users. Alternatively, the tether 14 may have limited slack or no slack so that a user cannot move their chin in any significant manner toward their chest.

A slide member 24 may be installed on the back 16 of the helmet 12 so that one end of the tether 14 can slide from side to side when the player turns his/her head. The slide member 24 may include a snap, button, hook, or other attachment member for coupling with the first end of the tether 14. This way, the player's head may move freely from side to side.

The tether 14 normally remains loose until the head drops. Then the tether 14 becomes taut and will not allow the user to drop their chin 4. This, in turn, can help to avoid injuries to the player's neck 8 or head.

The system 10 may include a breakaway clip 28 that is positioned on the tether 14, or on or in connection with one of the attachment members. In the event that a competitor pulls outwardly on the tether 14, the breakaway feature 28 will allow the tether 14 to break. The tether 14 will not break when it encounters a head drop since the force applied in this instance will be substantially along the length L of the tether 14, or longitudinally. The breakaway feature 28 is designed to help to prevent injury to a player when the tether 14 is pulled on.

Referring to the drawings, FIG. 2 depicts an example helmet system 10 that includes a helmet 12 having an attachment member positioned on a rear 16 surface of the helmet, a fastener 30 positioned on the shoulder pads 18 of a user below the neck, and a tether 14 in the form of a cord coupled between the attachment member and the fastener 30. The attachment member is positioned above the neck of the user on the rear 16 surface of the helmet. The cord 14 is shown as having some slack, as indicated by the wavy line of the cord 14. The cord 14 extends generally length-wise along the length of a user's body. A breakaway member 28 is positioned on the cord 14 in approximately the center of the cord 14 and permits the cord 14 to be broken into two sections if an outward force is applied to the cord 14, such as by an opponent grabbing the cord 14. The breakaway member 28 will not break apart due to the existence of longitudinal tension.

The attachment member is coupled to the helmet 12 in approximately the center rear 48 of the helmet 12 and can be any type of attachment member, such as a snap, hook, rivet, button, or the like. The snap 60 or hook 62 may be permanently applied to the helmet 12. Alternatively, the attachment member may be coupled to the outer surface of the helmet 12 with hook and loop type tape 32 or an adhesive, such as an epoxy. A fastener 30 is also coupled to the shoulder pads 18 of a user. The fastener 30 may also be a snap, hook, rivet, button, or the like and may be coupled to the shoulder pads 18 permanently or via hook and loop type tape 32 or adhesive. The cord 14 has connectors 34, 36 at each end thereof for mating with the attachment member on the helmet 12 and the fastener 30 on the shoulder pads 18. The cord 14 has a length L that is suited for the particular user in order to prevent unwanted forward motion of the head. Cord length L and type may be customized depending upon the anatomy of a user.

FIG. 4 depicts the helmet system 10 of FIGS. 2 and 3, but shows the head dropping from a first position to a second position. In the first position (1), the cord 14 is loose and has some slack. In the second position (2) the cord 14 is taut and the user's chin is moved downwardly toward the chest. FIG. 5 shows the cord 14 in a taut position from the rear 16, with the breakaway clip 28 positioned on the cord 14. As is evident upon comparison of the prior art device in FIG. 1 and the helmet system 10 in FIG. 4, the user's chin is prevented or deterred from moving all the way to the user's chest. This will help to deter neck and head injuries in the event of a collision with another user or the ground, for example. Because the cord 14 has slack in its normal position, the user may easily move his/her head from side to side up to the amount of slack in the cord 14.

FIG. 6 shows an alternative example helmet system 10 that utilizes a helmet 12 that has a slider mechanism 40 coupled to the helmet 12, a tether 14 such as a strap, and a fastener 30 associated with a user's shoulder pads 18. The helmet 12 is a typical helmet and the slider mechanism 40 that is coupled to an exterior surface of the helmet 12. As with the example shown in FIGS. 2-5, the helmet 12 includes an attachment member 26, which in this case is coupled directly to the slider mechanism 40. The shoulder pads 18 have a fastener 30 for coupling to an end of the strap 14. The strap 14 has a breakaway connector 28, such as a barrel breakaway connector 28 positioned at a central location. The strap 14 also has an adjustment buckle 74 that allows for adjustment of the length of the strap 14 such that the strap 14 can be used with different user's having differing anatomies. The strap 14 has first and second connectors 34, 36 at each end thereof for mating with the attachment member 26 and the fastener 30. The first connector 34 mates with the attachment member 26 and the second connector 36 mates with the fastener 30.

Referring to FIGS. 8-10, the slider mechanism 40 may be coupled to the helmet 12 in any known way, such as by adhesive, hook and loop type tape 32, or by more permanent means, such as rivets 68, and the like. The slider mechanism includes a bottom plate 38 and a top plate 72. The bottom plate 38 is a flat, solid sheet of smooth material and the top plate 72 is a flat, smooth sheet of material that has an elongated slot 42 that runs along the length of the top plate 72. The ends of the bottom plate 38 and the top plate 72 may be coupled together in any known manner. A T-nut 44 is shown in FIGS. 6, 8, and 10 for holding the top and bottom plates 72, 38 together. Alternatively, a rivet 68 or welding may be used, among other attachment techniques. A washer or other spacer 76 may be positioned between the top and bottom plates 72, 38 in order to provide consistent spacing between the top and bottom plates 72, 38. The slider mechanism 40 may be made of metal, plastic, or the like.

A slide member 24 is positioned between the top and bottom plates 72, 38 of the slider mechanism 40 so that the attachment member 26 extends outwardly (away from the helmet 12 in a substantially perpendicular manner) through the slot 42 in the top plate 72. The slide member 24 may be any shape, as long as it's retained between the top and bottom plates 72, 38. The slide member 24 has a flat, smooth bottom surface 46 that glides along the bottom plate 38 such that the slide member 24 moves freely back and forth along the length of the slot 42. The attachment member 26 extends through the slot 42 in order to assist in maintaining the slide member 24 in the slot 42 and to permit the first connector 34 on the strap 14 to mate with the attachment member 26. Other types of slider mechanisms may be used, as known by those of skill in the art, including mechanisms with greater parts.

FIG. 6 shows how the slider mechanism 40 can be positioned at different locations on the helmet 12. In a first location, the slider mechanism 40 is positioned in the center rear 48 of the helmet 12. A second position is shown as being adjacent the bottom 50 of the helmet 12 near the neck. Other locations may also be utilized for positioning the slider mechanism 40. The slider mechanism 40 permits a user to move their head from side to side when the tether 14 is installed, even if there is not a significant amount of slack in the strap 14. FIG. 7 depicts different positions that the slide member 24 may be positioned in the slider mechanism 40 during use. The slide member 24 would be positioned at the left side 52 of the slider mechanism 40 when the user moves their head to the left and at the right side 54 of the slider mechanism 40 when the user moves their head to the right.

FIGS. 11-13 depict an alternative example helmet system 10 where the slider mechanism 40 is integral with the helmet 12. In this example, during molding of the helmet 12 into its final form, a slide track 56 is formed inside the interior of the helmet 12 and a slide member 24 is positioned inside the slide track 56, such as through a trap door inside the helmet (not shown). FIG. 11 shows the slot 58 positioned in an outer surface of the rear 16 of the helmet and FIGS. 12-13 show the slide track 56 inside the wall of the helmet 12. A slide member 24 is positioned in the slide track 56 and has a part that extends outwardly from the slot 58 in order to couple with a tether 14. The tether 14 may have a breakaway feature 28, such as a breakaway buckle. FIG. 12 shows the attachment member 26 as being a snap 60. FIG. 13 shows the attachment member 26 as being a hook 62 or loop. The space inside the slide track 56 is dimensioned and configured to permit easy sliding of the slider mechanism 40 inside the track 56 and to avoid dislodgment of the slider mechanism 40 from the track 56. Other types of slider mechanisms may be used, as known by those of skill in the art. Other mechanisms that permit side to side movement, or similar movement, may alternatively be used.

FIG. 14 depicts an alternative example helmet system 10 that utilizes a type of hook and loop material 32 to couple the slider mechanism 40 to the rear 16 of the helmet. Two possible positions are shown for attachment, one being higher on the helmet 12 and one being lower. The slider mechanism 40 has a hook and look material applied to a bottom surface of the bottom plate 38 for mating with a hook and loop material 32 that is positioned on an exterior surface of the helmet 12. The hook and loop type material 32 has a holding strength in order to withstand pressures and forces associated with the particular sport or activity at issue. FIG. 14 also depicts a harness 20 that can be used instead of coupling the safety strap 14 to the user's shoulder pads 18. The harness 20 includes a portion that goes around the torso 22 of the user and is pulled tight with a tightening element (not shown in FIG. 14). The strap 14 may include a loop 66 at one end and the harness 20 may be positioned through the loop 66. The loop 66 can be riveted 68 or snapped 60 to the harness 20. The loop 66 may permit some movement of the strap 14 along the length of the harness 20. The strap 14 can be coupled to the harness 20 in any known manner. Again, the strap 14 and harness 20 should be custom fit to a user based upon their size and anatomy. The harness 20 is particularly useful in sports that require helmets, but that do not require shoulder pads 18. The strap 14 may be coupled to other parts of the uniform, if desired, or at other locations on the body of the user.

FIG. 15 is similar to FIG. 14, but includes a length adjusting mechanism for allowing adjustment of the length of the strap 14. In this case, a buckle 74 is coupled to the first connector 34 of the strap 14 and permits the strap 14 to be lengthened and shortened. The first connector 34 of the strap 14 couples with the attachment member 26 of the slider mechanism 40 as with prior examples. FIG. 16 depicts the various layers of the connector, attachment member 26, and strap 14. In particular, a hook and loop type material 32 is applied to an outer surface of the helmet 12. A slider mechanism 40 is provided that has a bottom plate 38 and a top plate 72 with a slot 42 in it. A hook and look type material is adhered or otherwise applied to the bottom surface of the bottom plate 38 so that the slider mechanism 40 can couple to the hook and loop material 32 on the helmet 12. A slide member 24 is positioned between the bottom and top plates 38, 72 and the attachment member 26 extends through the slot 42 of the top plate 72. The strap 14 includes a buckle 74 that is used to lengthen and shorten the strap 14. The buckle 74 is connected to a snap 60, which is the first connector 34 of the strap 14.

The example system 10 may be used with any type of helmet 12, including football helmets, riding helmets, bicycle helmets, racing helmets, wrestling helmets, skiing helmets, or any other known helmets. The slider mechanism 40 may be sold as an add-on item to a helmet 12 and may be applied after purchase of the helmet 12. The tether 14 may be a plastic or fabric strap that is about 1 inches wide, or thinner or wider. Other types of straps or cords may be used. The term tether 14 is meant to encompass any type of strap, cord, or connecting member and to the extent that one or another of the terms is used herein, it should be understood that the other may apply interchangeably. It should be recognized that use of one implies that the other can alternatively be used.

A breakaway device 28 may be utilized with any of the examples described herein. The breakaway device 28 may be any known type of breakaway 28 that will break apart with an outward pulling force. Examples of breakaway devices 28 include buckles, connectors, or snaps, such as barrel buckles or connectors, center or side release buckles, clip locks, or tuck, press, flat, swingable, or covered buckles, among other devices. The breakaway device 28 may be made of plastic, or other materials.

One type of hook and loop type of material 32 that may be utilized is Dura Lock™, a 3M product. Other types of hook and loop or similar materials may be utilized to couple the slider mechanism 40 to the rear 16 of the helmet. In addition, epoxy or other adhesives may be used. Alternatively, manufacturers of helmets may manufacture a clip or pin that extends through the helmet (not shown) and that can be coupled to an external slider, if desired. Any known way to couple a device to a helmet 12 may be utilized.
